Question about Heating & Cooling
Can anyone advise how to solve condensation/damp problems in the roof of a static mobile home please? Due to damp/mould problems, I have replaced the ceiling in my mobile home, however, I noticed damp appearing on the new ceiling and took it down again. The metal roof above and attached insulation are soaking wet with what I believe to be condensation. I don't know how to resolve the problem. I am told that a 50cm gap needs to kept between the ceiling and the roof but the original insulation is actually touching the metal roof. It is very wet and I have found some mould in here as well. There was no vapour trap when I took the original ceiling down. I have added foil backed insulation boards between the rafters and there are air vents at one edge. Can anyone tell me what I'm doing wrong please?

You actually posted this in the wrong area but I am originally from Minnesota and can tell you. What's happening is called ice damming. They do make a drip edge type of thing that isn't very expensive for just this very thing. Go to Lowes, Homedepot, Menards etc. NOT your local trailer supply as they usually charge more. The clerk at the hardware store should be able to help you. Good luck. Please don't forget to give me a Fixya rating.

Check for plugged drains under cover on roof, sticking out at base of unit usually. It should be running off roof.

the manufacture is only required to supply the part free of charge thru its warranty period. the installing company probably would only give a 1year labor warranty and honor the pparts thru the manufacture for 5 years but unless you paid additinal for an extended labor warranty i dont think you are going to have much luck. Make sure you change your air filters every 30 days a dirty filter is one of the biggest causes of evap coils prematurely leaking. Sorry wish i could be more help.

The reason for the trap is to compensate for the negative pressure the drain line is under. Since the blower is pulling the air, if the trap wasn't there, then the drain wouldn't drain properly.
By having a trap, your blower is pulling air back through the trap while the condensate water is allowed to flow and drain.
With that being said, if you have water forming in your emergency pan, its an indication that the main drain line is clogged up. If you know where the drain line exits the home, take a small shop van and vacuum out the drain line. If its really backed up, it will sound like a golf ball through a garden hose.
If your trap has a clean-out installed, I would recommend pouring some hot water and bleach combination down the trap itself after you have cleared and flushed the drain. The bleach will assist in killing any mold/mildew that has accumulated in the drain.
Also, while your in your attic, ensure your emergency pan has a float switch and that its operating properly.
